Stuttering

Hello, when I was young (2011/2012) Minecraft was my favorite game of all time.
Now, I would like to fall back into my childhood so why not ?
I launch Minecraft, and 30 seconds later... this game, is now poorly optimized, and stuttering af?! Minecraft/Microsoft what is going on !!!!
Right now, you just destroyed my childhood game... :'(

Please Microsoft, make Minecraft great again !
Oh and btw, I will NOT play the Windows 10 version (microsoft store)
